    I’ve worked on a couple of those 6’s from the 70s that had similar issues, even after doing all the usual ignition and carb stuff stuff. It turned out to be a bad upper crankshaft seal (too much air into crankcase). Any evidence of oil up under armature plate, points, flywheel?

    Thanks for all suggestions — I rebuilt carb w/ OEM kit — hope they provided correct gasket. Will continue to noodle away with your suggestions as a guide — and advise. Thanks!
